Trigger Controls
1 Press [AutoScale] to return to a simple setup.
2 Set the time base to 50 ns/div.
3 Rotate the trigger level knob up and down. The trigger level is
displayed while it is adjusted.
If the trigger level is above or below the signal, the oscilloscope
will force a trigger and display a waveform when in Auto mode.
Auto is a useful trigger mode to use when unsure of the exact
waveform, as activity will be displayed making it easy to better
configure the oscilloscope’s settings and trigger level.
When triggers are forced, the white Auto LED (in the Run Control
section) is lit. When the oscilloscope finds the trigger event, the
white Trig’d LED is lit.
4 Press the [Sweep] key in the trigger section to toggle from Auto
mode to Tri g’d mode.
5 Now, move the trigger level up and down.
The oscilloscope only triggers when a valid trigger condition
exists. Use the Tri g’d mode when you want to set a specific trigger
condition and capture waveforms only when those conditions are
met.
When waiting for trigger, only the white Arm’d LED is lit. When the
oscilloscope finds the trigger event, the white Trig’d LED is also lit.
